2.4
Counter of received messages (30004)
32-bit register with the number of valid Modbus received messages by the module from
last powered up. The value is reset after power cycle or after changing transmission
parameters (speed, stop bits, parity, etc.).
2.5
Counter of error messages (30006)
32-bit register with the number of error Modbus received messages by the module from
last powered up. The value is reset after power cycle or after changing transmission
parameters (speed, stop bits, parity, etc.).
2.6
Counter of sent messages (30008)
32-bit register with the number of Modbus sent messages by the module from last powered
up. The value is reset after power cycle or after changing transmission parameters (speed,
stop bits, parity, etc.).
2.7
Up time (30012)
This 16-bits register contains module working time in seconds from last power up or
